“We are pleased to have now dosed the first patient in our 300 mg dose group. This dose group will provide more information on the drug exposure vs adverse event relationship which is critical to FDA approval given FDA’s Project Optimus Oncology initiative. In addition, the data obtained from this dose group will help us to better understand how PCS6422 alters capecitabine metabolism to form more cancer-killing metabolites and fewer metabolites that only cause dose-limiting side effects,” said Dr. David Young, President and CEO of Processa.
